Derive coefficients for a peaking filter with a given amplitude and bandwidth. All coefficients are calculated as described in Zolzer'sDAFX book (p. 50 - 55). This algorithm assumes a constant Q-termis used through the equation.Usage: [B,A] = peaking(G, Fc, Q, Fs); G is the logrithmic gain (in dB) FC is the center frequency Q is Q-term equating to (Fb / Fc) Fs is the sampling rateThe typical usages is multi-band equalization where each band has it's own peaking filter.
